| 摘要 | The invention relates to an optically transparent polymer film or extrudate product made of a polymer composition comprising a semi-crystalline polyamide having a melting temperature of at least 270° C. or a blend of the semi-crystalline polyamide (A) and a second polymer (B), and optionally at least one additive, wherein the semi-crystalline polyamide (A) is present in an amount of more than 50 wt. %, relative to the total weight of the polymer composition, the polymer composition in the optically transparent polymer film or extrudate product has a melting temperature (Tm-C) in the range of 270-340° C., and wherein the film or a part of the extrudate product has a haze of less than 12% and a light transmittance, of at least 88% measured with the method according to ASTM D1003A. | ||

| 主权项 | 1. An optically transparent extrudate product made of a polymer composition comprising at least 60 wt. %, relative to total weight of the polymer composition, of a semi-crystalline polyamide (A) having a melting temperature TmA of at least 270° C., wherein the semi-crystalline polyamide (A) is a semi-crystalline semi-aromatic polyamide or a blend thereof with a semi-crystalline aliphatic polyamide, and wherein the polymer composition has a melting temperature TmC of at least 270° C., and the extrudate product has a haze of less than 12% and a light transmittance of at least 88%, measured with the method according to ASTM D1003A. | ||
